Result of TRIZ
2-2. What is the result of the TRIZ activity?
8
This theme: Attempt activity of idea
・ A lot of good ideas are generated ・ The product plan is constructed ・ The stage of the product development is advanced to the next step
The result of TRIZ: enough only in the place where the idea is grmerated. The team works.
It is assumed that a good idea did not come out and puts it in drawing out.
It doesn't often get on a concrete development schedule though it finished up in the product plan idea.
It doesn't stay in idea generation, and "Settling and selection of the idea" is done. It is necessary to construct the product plan idea that advances the product
development.

3-2. Problem of centering on the Pugh Method
12
This theme: It introduces settling some ideas and the attempt of the selection.
In a standard idea settling and the selection, there are various problems.
The idea (idea that cannot be made the best use of) to be thrown away is abundant.
It takes time.
Is the idea uniting (combination) reasonable? The synergy?
Is the idea selection reasonable? Is it arbitrary?
Are the concept and the development scenario reasonable?

Definite plan-making
(idea settling)
The idea uniting It doesn't aim.
Selected idea
Screwing in One direction assembly
Do not aim at the idea uniting, and the definite plan-making to the standard method
The whole image is drawn.
・Storage check ・The lack parts are drawn.
The point is three-dimensionally drawn.
・A necessary device is added.
The definite plan: It raises the level of a fragmentary idea to the approved idea.
Definite plan 1 Selection idea: No. XX Making: **
The selected idea It racks one's brains in passing it.
- The idea uniting is not forcibly thought.

6-2. Summary
28
1. Idea settling and selection are equally important to idea generation in the TRIZ activity 2. The method of some "Idea settling and selection" is tried, and it proposes the portfolio, the idea selection judgment line, the idea review, and the definite plan-making, etc. as a series of procedure for maximizing the result of the TRIZ activity - Wishing to contribute for the references of the people who promote the TRIZ activity
